Description

The present invention is a transmitter apparatus performs communication via a network, a control method thereof and a program.

  Currently, the spread of IP (Internet Protocol) telephones is progressing, and in addition to the conventional G3-FAX (facsimile) via the telephone network, FAX which performs FAX communication via the IP network has appeared. As a method of FAX communication performed via the IP network, there are a deemed voice method, a real-time method (ITU-T.38 method), and a mail method (ITU-T.37 method).

  With regard to FAX, various techniques for preventing important information such as confidential information from leaking to the outside due to erroneous transmission have been proposed. For example, there is a technique for inputting a destination telephone number twice.

  As for the real-time FAX, a technique for preventing FAX transmission to a terminal not intended by a caller has been proposed (see Patent Document 1). In this technique, when a substitute address of a destination address is notified from a SIP (Session Initiation Protocol) server, communication is interrupted and FAX transmission to the substitute address is restricted. Further, when the notified alternative address corresponds to a preset permitted address, communication can be permitted and FAX transmission to the alternative address can be performed.

  In addition, regarding e-mail, a technique for restricting transmission of e-mail to the destination address based on the domain of the destination address has been proposed in order to prevent leakage of important information to the outside due to erroneous transmission. (See Patent Document 2).

  Although the configuration of the MFP 100 has been described here, the other MFPs 101 and 110 have the same configuration, and the description thereof is omitted.

  Next, data set in the ENUM server 105 will be described with reference to FIG. FIG. 3 is a diagram showing data set in the ENUM server 105 of FIG.

  In the ENUM server 105, data 300 to 312 as shown in FIG. Here, each of the data 300 to 303 is data related to the MFP 100. The data 300 includes a character string in which the telephone number of the MFP 100 is reversed and separated by dots, and e164. It is data consisting of a character string of arpa. Data 301 indicates the SIP-URI (sip: info@abc.co.jp) of the MFP 100, and is weighted with “100”. Data 302 is the T.P. This is data with 37 mail addresses (ifax@abc.co.jp) and weighted with “102”. Data 303 indicates the FAX telephone number (+ 81-3-0000-0001) of the MFP 100 and is weighted with “104”.

  Therefore, when the telephone number “+ 81-3-0000-0001” is inquired to the ENUM server 105, the above data is returned to the inquiry destination. In the inquiry destination, data having a low weighting value among the data 301 to 303 is used as the destination. Here, when a failure such as disconnection occurs in the communication of the used destination, the next weighted data is used as the destination.

  Each data 304 to 306 is data related to the MFP 101. Here, the data 304 includes a character string in which the telephone number of the MFP 101 is reversed and separated by dots, and e164. It consists of a character string of arpa. The data 305 indicates the SIP-URI (sip: sales@abc.co.jp) of the MFP 101 and is weighted with “100”. Data 306 includes T.P. This is data with 37 mail addresses (sales-fax@abc.co.jp) and weighted with “102”.

  Therefore, when the telephone number “+ 81-3-1234-5678” is inquired to the ENUM server 105, the above data is returned to the inquiry destination. At the inquiry destination, data having a low weighting value among the above data is used as the destination. Here, when a failure such as disconnection occurs in the communication of the used destination, the next weighted data is used as the destination.

  Each data 307 and 308 is data relating to the G3-FAX apparatus 109. The data 307 includes a character string in which the telephone number of the G3-FAX apparatus 109 is reversed and separated by dots, and e164. It consists of a character string of arpa. Data 308 indicates the FAX telephone number (+ 81-3-0000-1111) of the G3-FAX apparatus 109, and is weighted with “100”.

  Accordingly, when the telephone number “+ 81-3-0000-1111” is inquired to the ENUM server 105, the above data is returned to the inquiry destination.

  Data 309 to 312 are data related to the MFP 110. The data 309 includes a character string in which the telephone number of the MFP 110 is reversed and separated by dots, and e164. It consists of a character string of arpa. The data 310 indicates the SIP-URI (sip: info@abc.com.cn) of the MFP 110 and is data weighted with “100”. Data 311 includes T.P. This is data with 37 mail addresses (info@abc.com.cn) and weighted with “102”. Data 312 represents the FAX telephone number (+ 86-10-2222-3333) of the MFP 110 and is weighted with “104”.

  Accordingly, when the telephone number “+ 86-10-2222-3333” is inquired to the ENUM server 105, the above data is returned to the inquiry destination. At the inquiry destination, data having a low weighting value among the above data is used as the destination. Here, when a failure such as disconnection occurs in the communication of the used destination, the next weighted data is used as the destination.

  Next, setting of FAX transmission restriction will be described with reference to FIG. FIG. 4 is a view showing an example of a FAX transmission restriction setting screen displayed on the operation unit 133 of the MFP 100 in FIG.

  In the present embodiment, setting can be made so as to restrict desired FAX transmission among a plurality of FAX transmissions, and the authority to perform the setting is given only to the system administrator. Therefore, when the FAX transmission restriction is set in the MFP 100, only the system administrator displays the FAX transmission restriction setting screen on the operation unit 133, and sets a desired FAX transmission restriction using the FAX transmission restriction setting screen. Can do. On the other hand, other users cannot display and browse the FAX transmission restriction setting screen.

  As described above, the MFP 100 has a FAX transmission function that performs each of G3-FAX transmission, I-FAX transmission, and IP-FAX transmission. The system administrator can set a desired FAX transmission restriction among the above FAX transmissions.

  When restricting desired FAX transmission among G3-FAX transmission, I-FAX transmission, and IP-FAX transmission in the MFP 100, the system administrator performs an operation to display a FAX transmission restriction setting screen on the operation unit 133 of the MFP 100. . By this operation, for example, a screen 350 as shown in FIG. 4 is displayed on the operation unit 133 as a FAX transmission restriction setting screen.

  The FAX transmission restriction setting screen 350 is a screen for setting restrictions on FAX transmission (G3-FAX transmission, IP-FAX transmission, I-FAX transmission) used when performing FAX transmission to an overseas transmission destination. Here, check boxes 351 to 353 are provided for the G3-FAX transmission restriction, the IP-FAX transmission restriction, and the I-FAX transmission restriction, respectively. When a desired check box is checked among these check boxes 351 to 353, FAX transmission of the checked check box is restricted.

  For example, if the G-3 FAX transmission restriction check box 351 is checked, it is determined whether or not the transmission destination is an overseas transmission destination based on the telephone number of the transmission destination, and the transmission destination is an overseas transmission destination. If so, G-3 FAX transmission is restricted. If the IP-FAX transmission restriction check box 352 is checked, it is determined whether or not the transmission destination is an overseas transmission destination based on the telephone number of the transmission destination, and the transmission destination is an overseas transmission destination. If so, IP-FAX transmission is restricted. Details of the IP-FAX transmission restriction will be described later. If the I-FAX transmission restriction check box 353 is checked, it is determined whether or not the destination is an overseas destination based on the email address of the destination, and the destination is an overseas destination. If so, I-FAX transmission is restricted.

  Also, a check box 354 for setting a destination domain (transmittable domain) that permits IP-FAX transmission and I-FAX transmission, and a domain name of a destination that permits IP-FAX transmission and I-FAX transmission. Input fields 355 and 356 are included. Also included are check boxes 357 and 358 for setting whether or not to permit the sub-domain of the input domain name as a destination for permitting IP-FAX transmission and I-FAX transmission.

  In this example, the domain name “abc.co.jp” is input in the input field 355, and the check box 356 for permitting the subdomain is checked. Therefore, in this case, FAX transmission (IP-FAX transmission or I-FAX transmission) is permitted even to a subdomain such as “sales.abc.co.jp”.

  Also, a check box 359 for setting a destination domain (transmission restriction domain) for restricting IP-FAX transmission and I-FAX transmission, and a destination domain name for restricting IP-FAX transmission and I-FAX transmission. Input fields 360 and 361 are included. Also included are check boxes 362 and 363 for setting whether or not to restrict the subdomain of the input domain name as a destination for restricting IP-FAX transmission and I-FAX transmission.

  In this example, the domain name “abc.co.jp” is input in the input field 360, and the check box 362 for permitting the subdomain is checked. Therefore, in this case, FAX transmission (IP-FAX transmission or I-FAX transmission) is also restricted to subdomains such as “sales.abc.co.jp”.

  Also included is a check box 364 for setting transmission restrictions when the country information of the destination telephone number and the country information of the destination domain do not match. When the check box 364 is checked, it is determined whether the country information of the destination telephone number and the country information of the domain do not match. Here, if it is determined that the country information of the destination telephone number and the country information of the domain do not match, IP-FAX transmission is restricted.

  In addition, when the check box 364 is checked, a check box 365 for setting the “.com” domain (specific domain) not to be determined as a US domain is provided. Originally, the domain “.com” is a US domain, but may be expanded to other countries. Therefore, when the check box 365 is checked, the domain “.com” is used when determining whether or not the country information of the destination telephone number and the country information of the domain do not match. It is avoided to judge. That is, the domain “.com” is not subject to determination as to whether the country information of the destination telephone number and the country information of the domain do not match.

  The contents set using the FAX transmission restriction setting screen 350 are held in the hard disk 137.

  Next, a case where IP-FAX transmission is performed from the MFP 100 to the MFP 101 will be described with reference to FIG. FIG. 5 is a diagram illustrating a sequence in the case where IP-FAX transmission is performed from the MFP 100 to the MFP 101 in which the MFP 110 is set as a reception destination.

  Here, it is assumed that the user of the MFP 101 is set to receive data transmitted by FAX with the MFP 110 instead of the MFP 101. When this setting is performed, as shown in FIG. 5, “REGISTER” is transmitted from the MFP 101 to the SIP server 104 (400). This “REGISTER” is a message for setting the receiving destination in the MFP 110. Upon receiving this “REGISTER”, the SIP server 104 sets the destination to be MFP 110 for the FAX transmission whose destination is the MFP 101, and returns “200 OK” to the MFP 101 (401). In this way, setting is made so that the MFP 110 receives the data transmitted by the FAX transmission with respect to the FAX transmission with the MFP 101 as the reception destination.

  When the MFP 100 executes IP-FAX transmission with the MFP 101 as the recipient, the MFP 100 designates “+ 81-3-1234-5678” which is the telephone number of the MFP 101 and makes an inquiry to the ENUM server 105 (402). . Upon receiving this inquiry, the ENUM server 105 returns the data 305 shown in FIG. 3 (403).

  The MFP 100 sets data having a low weighting value among the data 305 and 306 returned from the ENUM server 105, that is, “sip: sales@abc.co.jp” as the destination of the IP-FAX transmission. Then, the MFP 100 issues a connection request to “sip: sales@abc.co.jp” together with the INVITE command to the SIP server 104 (404). Upon receiving this connection request, the SIP server 104 issues “INVITE” to the MFP 110 instead of the MFP 101 (405). In addition, the SIP server 104 returns a provisional message “100 Trying” indicating that “INVITE” is being executed to the MFP 100 (406).

  Upon receiving the “INVITE”, the MFP 110 transmits a provisional message “180 Ringing” to the SIP server 104 (407). Receiving this provisional message, the SIP server 104 transmits a provisional message of “180 Ringing” to the MFP 100 (408).

  When the MFP 110 is ready for reception, the MFP 110 returns “200 OK” to the SIP server 104 (409), and the SIP server 104 returns “200 OK” to the MFP 100 (410). Here, “200 OK” from the SIP server 104 includes a contact header (or Accept-contact header), and this header includes information on the MFP 110 that actually performs communication (sip: info@abc.com. cn) is described.

  Based on the information in the contact header, the MFP 100 determines whether there is no problem even if transmission is performed to the destination indicated by the information. If it is determined that there is no problem, the MFP 100 transmits “ACK” to the MFP 111. (411).

  After the transmission of “ACK”, a media session is started between the MFP 100 and the MFP 110 (412). Image data is transmitted according to the 38 protocol.

  After the transmission of the image data is completed (after the media session is completed), the MFP 100 transmits “Bye” to the SIP server 104 (414), and the SIP server 104 transmits “Bye” to the MFP 110 (415). . Receiving “Bye”, the MFP 110 ends the reception process and transmits “200 OK” to the SIP server 104 (416). Upon receiving this “200 OK”, the SIP server transmits “200 OK” to the MFP 100 (417).

  Receiving this “200 OK”, the MFP 100 confirms that the transmission has ended normally, and ends the transmission process. At this time, the MFP 100 records the information “sip: info@abc.com.cn” actually communicated with the telephone number “+ 81-3-1234-5678” in the transmission log. In addition, a transmission result report describing the information recorded in the transmission log and the first page image of the transmission image is printed and output.

  Next, a case where the MFP 100 for which IP-FAX transmission restriction is set performs IP-FAX transmission to the MFP 101 will be described with reference to FIG. FIG. 6 is a diagram illustrating a sequence in a case where the MFP 100 in which restrictions on IP-FAX transmission are set performs IP-FAX transmission to the MFP 101 in which the MFP 110 is set as a reception destination.

  Here, it is assumed that restrictions on IP-FAX transmission are set in MFP 100 using the FAX transmission restriction setting screen (FIG. 4). Further, it is assumed that the MFP 101 is set to receive data transmitted by FAX from the MFP 110 instead of the MFP 101.

  Here, as shown in FIG. 6, the sequence in the case where the MFP 101 is set to receive data transmitted by FAX with the MFP 110 instead of the MFP 101 is the same as the sequence shown in FIG. 5 described above.

  When the MFP 100 performs IP-FAX transmission with the MFP 101 as the recipient, the MFP 100 first designates “+ 81-3-1234-5678” which is the telephone number of the MFP 101 and makes an inquiry to the ENUM server 105. (402). After this inquiry, the sequence from the SIP server 104 until “200 OK” is returned to the MFP 100 (410) is the same as the sequence shown in FIG.

  The MFP 100 restricts IP-FAX transmission for the destination information based on the destination information (sip: info@abc.com.cn) of the contact header (or Accept-contact header) included in the “200 OK”. It is determined whether or not it has been done. Here, since the domain of the destination information (sip: info@abc.com.cn) in the contact header is a transmission restricted domain (FIG. 4), it is determined that IP-FAX transmission is restricted.

  Therefore, the MFP 100 transmits “Bye” to the SIP server 104 (414), and the SIP server 104 transmits “Bye” to the MFP 110 (415). The MFP 110 that has received this “Bye” transmits “200 OK” to the SIP server 104 (416), and the SIP server 104 transmits “200 OK” to the MFP 100 (417). Receiving “200 OK”, the MFP 100 ends the process without performing IP-FAX transmission. At this time, the MFP 100 includes, in the transmission log, information indicating a transmission error due to transmission restriction, a telephone number “+ 81-3-1234-5678”, and an actual destination “sip: info@abc.com.cn”. The destination information including the URL is recorded.

  Next, the operation when the MFP 100 performs FAX transmission will be described with reference to FIGS. 7 and 8 are flowcharts showing an operation procedure when the MFP 100 performs FAX transmission. The procedures of the flowcharts shown in FIGS. 7 and 8 are executed by the CPU 130 according to programs stored in the ROM 131 or the hard disk 137.

  When the user performs FAX transmission using the MFP 100, a FAX transmission screen (not shown) is displayed on the operation unit 133 of the MFP 100 by the user's operation. This FAX transmission screen displays FAX transmission information such as FAX transmission destination information (transmission destination telephone number, transmission destination e-mail address), and information indicating the FAX system to be used (G3-FAX, IP-FAX, I-FAX). It is a screen for inputting the information regarding. When the start key is pressed after the information related to FAX transmission is input, processing for FAX transmission is started.

  When the start key is pressed, as shown in FIG. 7, the CPU 130 acquires information on the FAX transmission input on the FAX transmission screen (step S501). Here, as described above, the input transmission destination information (transmission destination telephone number or electronic mail address) and FAX system (G3-FAX, IP-FAX, I-FAX) are acquired. Then, the CPU 130 controls the scanner 134 so as to read the document (step S502).

  Next, the CPU 130 determines whether or not the input FAX method is G3-FAX (step S503). When it is determined that the input FAX method is G3-FAX, the CPU 130 determines whether or not the transmission destination is an overseas transmission destination based on the input transmission destination information (step S504). . When the input FAX method is G3-FAX, a transmission destination telephone number is input as the transmission destination information.

  When it is determined in step S504 that the transmission destination is an overseas transmission destination, the CPU 130 determines whether or not the G3-FAX transmission restriction (FIG. 4) is set (step S505). When it is determined that the G3-FAX transmission restriction is not set, the CPU 130 performs G3-FAX transmission (step S506). Here, the image data read by the scanner 134 is sent from the fax unit 140 to the telephone line 142. Subsequently, the CPU 130 records a transmission log and outputs a transmission result report (step S513). Here, information indicating the end of transmission, transmission destination information (telephone number), etc. are recorded in the transmission log, and the transmission result in which the information recorded in the transmission log and the first page image of the transmission image are described The report is printed and output. Then, the CPU 130 ends this process.

  When it is determined in step S504 that the transmission destination is not an overseas transmission destination, the CPU 130 performs G3-FAX transmission (step S506), records a transmission log, and outputs a transmission result report (step S513). Then, the CPU 130 ends this process.

  If it is determined in step 505 that the G3-FAX transmission restriction is set, the CPU 130 displays a message indicating the G3-FAX transmission restriction on the operation unit 133 (step S512). Subsequently, the CPU 130 records information indicating a transmission error due to transmission restriction and destination information (telephone number) in the transmission log, and prints and outputs a transmission result report in which the information recorded in the transmission log is described. (Step S513). Then, the CPU 130 ends this process.

  When it is determined in step S503 that the input FAX method is not G3-FAX, the CPU 130 determines whether or not the input FAX method is I-FAX (step S507). When it is determined that the input FAX method is I-FAX, the CPU 130 determines whether or not the transmission destination is an overseas transmission destination based on the input transmission destination information (step S508). . Here, when the input FAX method is I-FAX, an e-mail address is input as the destination information. Therefore, it is determined whether the transmission destination is an overseas transmission destination based on the country information of the domain of the electronic mail address.

  If it is determined in step S508 that the transmission destination is an overseas transmission destination, the CPU 130 determines whether or not I-FAX transmission restriction is set (step S509). If it is determined that the I-FAX transmission restriction is not set, the CPU 130 corresponds to the transmission restriction domain (FIG. 4) in which the domain of the transmission destination information (e-mail address) is set. Is determined (step S510). When it is determined that the domain of the e-mail address does not correspond to the transmission restriction domain, the CPU 130 performs I-FAX transmission using the e-mail address (step S511). Here, an e-mail with the image data read by the scanner 134 attached to the e-mail address is transmitted. Subsequently, the CPU 130 records a transmission log and outputs a transmission result report (step S513). Information indicating the end of transmission, transmission destination information (e-mail address), and the like are recorded in the transmission log, and information recorded in the transmission log is described in the transmission result report. Then, the CPU 130 ends this process.

  If it is determined in step S508 that the transmission destination is not an overseas transmission destination, the CPU 130 determines whether the domain of the transmission destination information (e-mail address) corresponds to the transmission restriction domain (step S508). S510).

  If it is determined in step S509 that the I-FAX transmission limit is set, the CPU 130 displays a message indicating the I-FAX transmission limit on the operation unit 133 (step S512). Subsequently, the CPU 130 records information indicating a transmission error due to transmission restriction and transmission destination information (e-mail address) in the transmission log, and prints a transmission result report describing the information recorded in the transmission log. Output (step S513). Then, the CPU 130 ends this process.

  If it is determined in step S510 that the domain of the destination information (e-mail address) corresponds to a transmission restriction domain, the CPU 130 displays a message indicating restriction on I-FAX transmission (step S512). ). Subsequently, the CPU 130 records information indicating a transmission error due to transmission restriction and transmission destination information (e-mail address) in the transmission log, and prints a transmission result report describing the information recorded in the transmission log. Output (step S513). Then, the CPU 130 ends this process.

  If it is determined in step S507 that the input FAX method is not I-FAX, the input FAX method is IP-FAX. In this case, as shown in FIG. 8, the CPU 130 determines whether or not the transmission destination is an overseas transmission destination based on the input transmission destination information (step S514). Here, when the input FAX method is IP-FAX, a telephone number is input as the destination information. Therefore, it is determined whether the transmission destination is an overseas transmission destination based on the country information of the telephone number.

  When it is determined in step S514 that the transmission destination is an overseas transmission destination, the CPU 130 determines whether or not IP-FAX transmission restriction (FIG. 4) is set (step S515). If it is determined that the IP-FAX transmission restriction is not set, the CPU 130 performs ENUM processing (step S516). As described above, the ENUM process is a process of inquiring the ENUM server 105 by designating the destination telephone number, and acquiring the destination information (network address) returned from the ENUM server 105 in response to this inquiry. (402, 403 in FIG. 5 or FIG. 6). Here, if the acquired destination information (network address) is in the IP address format, the domain of the destination information (network address) is acquired by reverse DNS lookup. Similarly, when it is determined in step S514 that the transmission destination is not an overseas transmission destination, the CPU 130 similarly performs ENUM processing (step S516).

  Next, the CPU 130 determines whether or not the domain of the transmission destination information corresponds to the transmission restriction domain set (step S517). When it is determined that the domain of the transmission destination information does not correspond to the transmission restriction domain, the CPU 130 performs SIP processing (step S518). This SIP processing is processing for performing call control according to the sequence of 403 to 410 in FIG. 5 or FIG. Then, the CPU 130 obtains transmission destination information included in the information (contact header or Accept-Contact header information) returned from the SIP server 104 by the SIP processing (step S519).

  Next, the CPU 130 determines whether or not the acquired transmission destination information is in the IP address format (step S520). If it is determined that the acquired destination information is in the IP address format, the CPU 130 performs reverse DNS lookup and acquires the domain of the destination information (step S521). Then, the CPU 130 determines whether or not the domain of the transmission destination information corresponds to the transmission restriction domain set (step S522). If it is determined in step S520 that the acquired destination information is not in the IP address format, the CPU 130 determines whether the domain of the destination information corresponds to a transmission restriction domain. (Step S522).

  If it is determined in step S522 that the domain of the destination information does not correspond to a transmission restricted domain, the CPU 130 determines whether or not transmission restriction (FIG. 4) when country information does not match is set (FIG. 4). Step S524). The setting of transmission restriction when the country information does not match is a setting for performing transmission restriction when the country information of the destination telephone number and the country information of the IP address domain do not match. For example, in the case of FIG. 6, the destination telephone number “+ 81-3-1234-5678” is a telephone number in Japan, but the destination information “sip: info@abc.com.cn” Country information is China. Therefore, in this case, the country information of the destination telephone number does not match the country information of the domain of the destination IP address.

  If it is determined in step S524 that the transmission restriction is set when the country information does not match, the CPU 130 determines whether or not to restrict the IP-FAX transmission to the transmission destination (step S525). Here, it is determined whether or not to restrict IP-FAX transmission according to the determination result of whether or not the country information of the destination telephone number and the country information of the destination information domain do not match. . Here, in determining whether the country information of the destination telephone number and the country information of the destination information domain do not match, a specific domain (".com" domain in FIG. 4) is not set as a determination target. If it is set, the specific domain is not determined.

  If it is determined in step S525 that IP-FAX transmission to the transmission destination is not restricted, the CPU 130 starts a media session with the transmission destination apparatus (MFP 110) (step S526). Then, the CPU 130 waits for the end of the media session (end of image data transmission) (step S527).

  When the media session ends, the CPU 130 transmits “Bye” and performs reception processing of the transmission result (step S528). Subsequently, the CPU 130 records information such as transmission destination information, transmission start time, and sender information in the transmission log, as well as transmission in which the information recorded in the transmission log and the first page image of the transmission image are described. The result report is printed and output (step S529). Then, the CPU 130 ends this process.

  If it is determined in step S524 that the transmission restriction when the country information does not match is not set, the CPU 130 starts a media session with the destination device (step S526).

  If it is determined in step S522 that the domain of the destination information corresponds to a transmission restriction domain, the CPU 130 displays a message indicating transmission restriction on the operation unit 133 (step S523). Then, the CPU 130 transmits “Bye” and performs reception processing of the transmission result (step S528). Next, the CPU 130 records a transmission log and outputs a transmission result report (step S529). Here, information indicating a transmission error due to transmission restriction and transmission destination information (network address) are recorded in the transmission log, and a transmission result report in which the information recorded in the transmission log is printed is output. . Then, the CPU 130 ends this process.

  If it is determined in step S525 that the IP-FAX transmission to the transmission destination is to be transmission restricted, the CPU 130 displays a message indicating the transmission restriction (step S523) and transmits “Bye” (step S528). Next, the CPU 130 records a transmission log and outputs a transmission result report (step S529). Then, the CPU 130 ends this process.

  When it is determined in step S515 that the IP-FAX transmission restriction is set, the CPU 130 displays a message indicating the transmission restriction (step S512), records a transmission log, and outputs a transmission result report (step S512). S513). Then, the CPU 130 ends this process.

  If it is determined in step S517 that the destination domain is not a transmission restriction domain, the CPU 130 similarly displays a message indicating transmission restriction (step S512), records a transmission log, and outputs a transmission result report. This is performed (step S513). Then, the CPU 130 ends this process.

  As described above, according to the present embodiment, it is possible to finely control restrictions on IP-FAX transmission by setting a transmission restriction domain.

  In the example shown in FIGS. 5 and 6, the MFP 100 uses the MFP 110 information (sip: info@abc.com.cn) described in “200 OK” transmitted from the MFP 110 via the SIP server 104. Although acquired, other modes may be used. That is, instead of the MFP 110, the SIP server 104 may notify the MFP 100 of information (sip: info@abc.com.cn) of the MFP 110 that is the actual communication destination.

(Second Embodiment)
Next, a second embodiment of the present invention will be described. The present embodiment has the same configuration as that of the first embodiment, and in the present embodiment, description will be made using the same reference numerals as those of the first embodiment.

  First, a case where the MFP 100 transfers data received from the MFP 101 to the MFP 110 in response to a transfer request from the MFP 101 will be described with reference to FIG. FIG. 9 is a diagram showing a sequence in the case where the MFP 100 transfers data received from the transmission source MFP 101 by IP-FAX communication to the MFP 110 in response to a transfer request from the MFP 101 in the second embodiment of the present invention. Here, the SIP server 104 is interposed between the MFP 100 and the MFP 110, but is omitted.

  When the MFP 101 transmits image data to the MFP 100 by IP-FAX transmission, as illustrated in FIG. 9, the MFP 101 sends the destination of the telephone number “+ 81-3-0000-0001” to the ENUM server 105. An inquiry is made (600). In response to the inquiry, the ENUM server 105 returns “sip: info@abc.co.jp” as the destination for the telephone number (601).

  Next, the MFP 101 issues “INVITE” to the MFP 100 (602). The MFP 100 returns “200 OK” to the MFP 101 following the provisional messages “100 Trying” and “180 Ringing” (603 to 605). Then, the MFP 101 learns that the MFP 100 is ready to receive data, and transmits “ACK” to the MFP 100 (606). Here, “INVITE” to “ACK” are SIP messages.

  After transmitting “ACK”, the MFP 101 starts a media session with the MFP 100, The image data defined by 38 is transmitted to the MFP 100 (607).

  After the end of the media session (after the end of image data transmission), the MFP 101 transmits “REFER” to the MFP 100 (608). This is a message for requesting the MFP 100 to transfer the received data to the MFP 110 of “sip: info@abc.com.cn”. Upon receiving the request, MFP 100 determines whether transfer of received data to MFP 110 is permitted or restricted. If it is determined that the transfer is permitted, the MFP 100 transmits “202 Accepted” to the MFP 101 (609). In addition, the MFP 100 transmits “INVITE” to the MFP 110 that is the data transfer destination (610).

  The MFP 110 that has received “INVITE” returns “200 OK” to the MFP 100 following the provisional messages “100 Trying” and “180 Ringing” (611 to 613). Receiving “200 OK”, the MFP 100 knows that the MFP 110 is ready to receive data and transmits “ACK” (614). Then, the MFP 100 starts a media session with the MFP 110, and the T.P. The image data is transmitted to the MFP 110 by the communication defined by 38 (615).

  After the media session ends, the MFP 100 transmits “Bye” to the MFP 110 (620). In response to the “Bye”, the MFP 110 returns “200 OK” to the MFP 100 (621). Thereby, the call between MFP 100 and MFP 110 is disconnected.

  In addition, the MFP 100 transmits “NOTIFY” to the MFP 101 to notify that the data transfer is completed (616). Following the “200 OK” (617), the MFP 101 transmits “Bye” to the MFP 100 (618). In response to the “Bye”, the MFP 100 transmits “200 OK” to the MFP 101 (619). Thereby, the call between MFP 100 and MFP 101 is disconnected.

  Next, a case where data transfer by MFP 100 is not permitted when MFP 100 transfers data received from MFP 101 to MFP 110 in response to a transfer request from MFP 101 will be described with reference to FIG. FIG. 10 is a diagram illustrating a sequence in a case where data transfer by MFP 100 is not permitted when MFP 100 transfers data received from MFP 101 to MFP 110 in response to a transfer request from MFP 101 in the second embodiment of the present invention. .

  As shown in FIG. The sequence until the image data defined by 38 is transmitted to the MFP 100 (607) is the same as the sequence shown in FIG.

  After the end of the media session (after the end of transmission of image data), the MFP 101 transmits “REFER” to the MFP 100 and transfers the received data to the MFP 110 to the MFP 110 (“sip: info@abc.com.cn”). Then, a request is made (608).

  Upon receiving the request, the MFP 100 sets the domain of the IP address “sip: info@abc.com.cn” assigned to the MFP 110 that is the transfer destination of the received data on the FAX transmission restriction setting screen (FIG. 4). It is determined whether or not it corresponds to the transmission restriction domain. Here, it is assumed that the domain of the IP address “sip: info@abc.com.cn” of the MFP 110 corresponds to the transmission restriction domain. In this case, the MFP 100 returns “503 Service Unavailable” to the MFP 101 (630), and does not transfer the received data.

  Receiving the “503 Service Unavailable”, the MFP 101 knows that no data has been transferred to the MFP 110 by the MFP 100 and transmits “Bye” to the MFP 100 (618). Upon receiving “Bye”, the MFP 100 returns “200 OK” to the MFP 101, and the MFP 100 ends the processing.

  Next, the operation of MFP 100 when MFP 100 transfers data received from MFP 101 to MFP 110 will be described with reference to FIG. FIG. 11 is a flowchart showing an operation procedure of MFP 100 when MFP 100 transfers data received from MFP 101 to MFP 110 in the second embodiment of the present invention. The procedure of the flowchart shown in FIG. 11 is executed by the CPU 130 of the MFP 100 according to the program stored in the ROM 131.

  When the MFP 100 receives the image data transmitted from the MFP 101, as shown in FIG. 11, the CPU 130 exchanges SIP messages (602 to 606 in FIG. 9 or FIG. 10) by SIP processing (step S701). .

  Next, the CPU 130 starts a media session. The image data defined by 38 is received (step S702). Here, the received image data is stored in the hard disk 137. Then, CPU 130 waits for the end of the media session (end of reception of image data transmitted from MFP 101) (step S703).

  When the media session ends, the CPU 130 receives a message transmitted from the MFP 101 and determines whether the message is “REFER” (step S704). If the received message is not “REFER”, the CPU 130 disconnects the call with the MFP 101 (step S714), and ends this process. Here, upon receiving “Bye” transmitted from the MFP 101, the CPU 130 returns “200 OK” to the MFP 101 in response to “Bye”.

  When it is determined in step S704 that the received message is “REFER”, the CPU 130 acquires transmission destination information of the transmission destination (transfer destination) of the received image data included in “REFER”. Then, the CPU 130 determines whether or not the domain of the acquired transmission destination information corresponds to the transmission restriction domain set (step S705). If it is determined that the domain of the destination information corresponds to a transmission restriction domain, the CPU 130 transmits “503 Service Unavailable” to the MFP 101 to notify that transfer is impossible (step S713). Then, the CPU 130 disconnects the call with the MFP 101 (step S714), and ends this process.

  If it is determined in step S705 that the destination domain does not correspond to a transmission restriction domain, the CPU 130 sets transmission restrictions when the country information of the destination telephone number and the country information of the domain do not match. It is determined whether or not (step S706).

  If it is determined in step S706 that transmission restriction is set when the country information does not match, the CPU 130 determines whether or not to restrict IP-FAX transmission to the transmission destination (step S707). . Here, it is determined whether or not to restrict IP-FAX transmission according to the determination result of whether or not the country information of the destination telephone number and the country information of the domain do not match. Here, if the setting is made such that a specific domain (the “.com” domain in FIG. 4) is not determined, the specific domain is not determined.

  If it is determined in step S707 that IP-FAX transmission to the transmission destination is not restricted, the CPU 130 exchanges SIP messages with the MFP 110 by SIP processing (step S708). Thereby, MFP 100 is connected to MFP 110 so as to be capable of IP-FAX transmission. In addition, the CPU 130 transmits “202 Accepted” to the MFP 101 in order to notify the MFP 101 that the received data is to be transferred to the requested destination.

  Next, the CPU 130 starts a media session for transmitting the received image data (step S709). Then, the CPU 130 waits for the end of the media session (end of image data transmission) (step S710). When the media session ends, the CPU 130 disconnects the call with the MFP 101 (step S711). Here, “Bye” is transmitted from MFP 100 to MFP 110, and “200 OK” is returned from MFP 110 to MFP 100.

  Next, the CPU 130 transmits “NOTIFY” to the MFP 101 and notifies the MFP 101 of the end of transfer (step S712). Then, the CPU 130 performs call disconnection processing with the MFP 101 (step S714), and ends this processing.

  If it is determined in step S707 that IP-FAX transmission to the destination is restricted, the CPU 130 notifies the MFP 101 that transfer is not possible (step S713). Then, the CPU 130 disconnects the call with the MFP 101 (step S714), and ends this process.

  As described above, according to the present embodiment, it is possible to finely control restrictions on IP-FAX transmission by setting a transmission restriction domain.

  In the first and second embodiments described above, an example in which no transmission processing is executed (that is, transmission is prohibited) is described when transmission is restricted, but other modes may be used. Absent. That is, when transmission is restricted, a message for allowing the user to confirm transmission may be displayed, and transmission processing may be executed after approval by the user.

  The object of the present invention can also be achieved by executing the following processing. That is, a storage medium that records a program code of software that realizes the functions of the above-described embodiments is supplied to a system or apparatus, and a computer (or CPU, MPU, etc.) of the system or apparatus is stored in the storage medium. This is the process of reading the code.

  In this case, the program code itself read from the storage medium realizes the functions of the above-described embodiments, and the program code and the storage medium storing the program code constitute the present invention.
